Abstract:
A measuring transducer comprising at least one measuring tube for conveying a flowing medium. The measuring tube vibrates at least at times during operation. A sensor arrangement, which serves to register oscillations of the at least one measuring tube. The measuring tube extends with an oscillatory length between an inlet-side, first measuring tube end, and an outlet-side, second measuring tube end, and, during operation, oscillates about an oscillation axis, which is parallel to or coincides with an imagined connecting axis which imaginarily connects the two measuring tube ends. By means of a first oscillation sensor, the sensor arrangement produces a first primary signal of the measuring transducer representing vibrations of the measuring tube, and by means of a second oscillation sensor the sensor arrangement produces a second primary signal of the measuring transducer representing vibrations of the measuring tube, wherein a length of a region of the first measuring tube extending between the first oscillation sensor and the second oscillation sensor defines a measuring length of the measuring transducer. The oscillation sensors of the sensor arrangement are placed in the measuring transducer in such a way that a measuring transducer sensitivity, SACT, referenced to a theoretical sensitivity at a maximum measuring length corresponding to the oscillatory length, as well as a signal amplitude, of the primary signals actually achieved during operation, referenced to a theoretically maximum possible signal amplitude, AMAX, at the location of maximum oscillation amplitude, fulfill the condition ℛ = A ACT A MAX · S ACT S MAX = ! Max .
